In a small bowl, combine warm water and active dry yeast. Let it sit for about 5 minutes to dissolve.
While the yeast is dissolving, take a stand mixer bowl and mix together warm milk, butter, and sugar using a spoon. Once the yeast is ready, add it to the milk mixture along with an egg and whisk until combined.
Then add flour and cinnamon, and mix using a hook attachment until the dough forms (it should form a dough on top of the bowl but it will be sticking to the bottom of the bowl, thats what we are looking for).
Add chopped raisins and mix until combined. Place the dough in a greased bowl, brush with melted butter, cover, and let it rise in a warm place for about 1 hour, or until it doubles in size.
After that, divide the dough into 12 pieces, roll each piece into a ball, and place them on a greased baking sheet lined with parchment paper or greased baking dish, making sure to leave space between each ball.
Cover with greased plastic wrap and let it rest in a warm place until it doubles in size, about 45 minutes to 1 hour.
Preheat the oven to 425°F. In a mixing bowl, whisk together flour, water, and sugar. Place the dough into a small ziplock bag, then snip the corner and slowly form crosses on top of the buns.
Bake for 18-20 minutes, or until golden in color.
To make a glaze, in a saucepan mix together water and sugar, bring it to a boil, reduce the heat, and simmer for 3 minutes, then brush it over the hot buns. Enjoy!
Notes
If you're using plastic wrap over the dough that is resting, don't forget to grease one side so it doesn’t stick.
You can also use a powdered sugar glaze to form the cross, but save this step for after baking.
I personally love the look of the glaze and the added sweetness, but feel free to skip it if you prefer. Alternatively, you can use an egg wash if you want a less sweet but still beautiful finish.
If you're using a glaze, consider adding some extra flavor to it by mixing powdered sugar and orange juice.
For those who want to spice things up, consider using nutmeg and allspice in addition to the cinnamon for some extra flavor.
